THR's 2012 Digital Power 50

In 1999, Parker co-founded Napster and forever changed the music industry. Five years later, he became Facebook's first president, bringing in the initial round of funding that would help launch a company now valued at nearly $100 billion. In 2010, he saw an opportunity to close a circle and invested $15 million in Spotify, a legal service for online music. Not every venture he has backed has been a winner, but as one-sixth of Founders Fund, which has issued four suites of capital since 2005 totaling more than $1 billion, the famous line attributed to Parker (as played by Justin Timberlake) in The Social Network seems particularly apt: "A million dollars isn't cool. You know what's cool? A billion dollars."
